"Application filed May 29,

To @ZZ wiomt may concern.'

z Be it known 'that LJOHN E. ScHLInrnn, a citizen of the United' States, residing at Pittsburgh, in the county of Allegheny and tt-ate of `Pennsylvania, lhave invented anew and useful Improvement in Tinning Apparatus,of which improvement the following isa specification. f

My invention relates to improvements. in tinning apparatus Iand .particularly to mechanism for feeding the sheets 4through the tinninfr bath.

The object fof' my invention: isv .to upro= duce a mechanism for .this purpose, in which simplicity of construction is attained, with a maximum degreeof yeliiciency` w l accomplish the object of the invention by' meansv of the apparatus"'hereinafter more fully described, reference being hadto` the accompanying drawings, formingwpart hereof inwhich: t

, Ilfig. 1 is a plan-view-of the apparatus.

Fig. 2 is a section on lines ll-lLofF-ig. A1; Fig. 3ds a detail of one pair of the yfeed rolls and their connections. f

Fig. l is a sectional. elevation on lines lV-IV of Fig. 1. l

Fig; 5 is a vertical vsection through the tinning Ybath parallelwith the rolls,` and bef tween the driving rolls andthe set of rolls adjacent. j I H Fig. 6 is a transverse yverticalsection'of the tinning vessel andframe, "the rollsand other parts being omitted.

Referring to said drawings, I show a receptacle of the usual construction, adapted to contain tinning material, i. e., the tinning material and the flux, and is divided,

as shown in the drawings, into two coin-y partments, 2, 3, which are connected by means of the guide conduit or oriiice, 4t, which extends widthwise and corresponds with the interior width of the apparatus. The said compartments, 2, 3, are adapted, as heretofore stated, to contain the tinning material, the forward portion of thecompartment, 3, containing the flux used in initially treating the'sheets before they. enter the tinning material. The sheet feeding mechanism comprises a table, 5, located at the `forward end, and is provided with regulating stops, 6, which are adapted to be adjusted or positioned to accommodate any required size of plate. Adjacent the lower ksideof said table, a pair yof drying rolls, compris- 19,20.y Serial No. 385,114.

ing the'rolls 7 andS, are located, the said rolls being supported in suitablev housings, 9., formed in the sides lof the frame 29. These rolls .are preferably formed rof rubber, for thepurpose of excreti'ng or removing moisture from the yplates :fed ythereto from the table, 5. The `plates are fed' from said rolls into land through the two sets of rolls,which y comprise the rolls, 10, 11i, 12,13 arranged tandem lin said vessehjreach set 'having a driven roll. The bearing Kendal/l, 15, Aof

vSaid rolls, 10, v12,;and'also the bearing end,

16,01 the roll, .7., .project through the side walls of a frame, 29, seated in said compartment, 3, the ends of each of said bearings respectively being provided `with cranks, 17, 18, the said :cranks -bei'ngconnected 'by rods, 19,20.4 It is noted vthat the cranks on one side `are arranged on a1diiferent angularity thany those on the opposite side, .the cranks ony one side .projecting in an opposite direction to thecranks :on the opposite side. The Ilower rolls-of each-set are frictionally` driven from vthe k:upper` rolls, which are positively driven through the frotation of the cranks, which arerdrivenfrom the sprocket wheels, l21, 21, which are mount-k ed upon the ends respectively ofthe roll, 7, a belt, 22, or othersuitable `anea'nsbeing employed to drive saidfsprocket wheels. yThe upper rolls lof yeachfset are .adjustably -maintained in. their housingsyby 'means ofthe springs, 23, the tension .ofwhich holdssaid rolls in -propcrrelation with the lower rolls and thereby adjusts and regulates thepressure upon the plates fed between the rolls and through the tinning material by the action of the upper or top rolls. Guides,`24,

are arranged to support the plates in their passing through the tinning bath, are forced or passedfthrou'gh the conduit, 4, which `connectsthe two compartments,"2 'and 8, and are carried through the conduit, 27, into and through the finishing rolls, 28, the said rolls being located in the upper end of the compartment, 2, in suitable housings. The sheet feeding mechanism is supported in the side members of the frame, 29, the upper -side members, 31, of said fra-me being secured in sockets formed in the bar or projection, 32, the upper portion of said frame, 29, having a recess, 33, in its under side, adapted to fit over the upper edge of the casting, forming the front Wall of the compartment, 3, and the lower portion of said frame, 29, being secured in the conduit or opening, 4, between the compartments, 2 and 8, whereby the said frame is securely seated in the compartment, 3, Without bolts or rivets. The sides of said frame Within the vessel project low enough in said vessel to form a compartment, X, in which the driving mechanism is located and adapted to operate; or an apron or extension, 30, Whichmay be either secured to or integral With the sides of saidv frame, projects to- Wards the bottom ofsaid vessel a sufficient distance to form said compartment,

Having described myv invention, What I claim and 'desire to secure by Letters Patent,

1. In a tinning apparatus, the combination of a vessel adapted to conta-in tinning material, ofa sheet feeding mechanism, com-` prising a plurality of sets of rolls located in said vessel, the 'bearing ends of the driven roll of each set having a crank mounted thereon, the said cranks being connected, whereby the said drivenrolls are rotated in the same direction, to feed the sheets jor plates through the tinning bath.

2. In a sheet tinning apparatus, the combination of a vessel adapted to contain tinning material, of a sheet feeding mechanism comprising a plurality of vsets of rolls, the upper roll of each set having a crank mounted on the end thereof, the saidl cranks on one side of the apparatus projecting in one direction and the cranks on the opposite side projecting` in an opposite direction, rods connecting said cranks and means to transmit motion to said cranks, whereby the plates or sheets are fed progressively through the tinning bath.

3. In a tinning apparatus, the combination of a vessel adapted to contain tinning material, a table or platform arranged at the front end of said vessel and provided with adjustable stops for the reception of tin plates placed thereon, in combination with sheet feeding mechanism comprising a series of sets of rolls, the upper roll of each of said sets having a crank mounted on the end thereof, the said cranks being connected, and means to transmit power to said cranks, whereby said rolls are adapted to feed sheets through the tinning bath.

4. In a tinning apparatus, the combination of a vessel, a sheet feedingI device seated in said vessel, comprising a frame, a series of feed rolls ournalled in the side Walls vof said frame, the said rolls having cranks projecting beyond the side Walls and an apron or extension to said side Walls extending to a point. substantially at the bottom of said vessel. n

5. In a tinning apparatus, the combination of a vessel, a sheet feeding device seated in .said vessel, comprising a frame, a series of feed rolls journalled in the side Walls of said frame, the said rolls having cranks proj ecting beyond the side Walls, the cranks on one side of the device projecting in one di-.

rection andthe cranks at the opposite projecting in an opposite direction, means connecting said cranks,and an apron or eXtension to said side walls extending to a point substantially at the bottom of said vessel.

In testimony whereof, I have hereunto signed my name inthe presence oftivo subscribing Witnesses.
